Some Italian, Portuguese, and Spanish Islands are in Africa, part of Azerbaijan and Georgia is in Europe, Panama/Colombia one of them is in the other continent can't remember which. France has islands in the Americas, Africa, and there is French Guiana which is an exclave of France and not a territory.
I was going to add French Guiana but I forgot, I've added it now put it's taking time to load...as for the rest of them that you mentioned, for the islands, I don't know if I want to put them because they're not part of the mainland...but then again I put Greece so idk. But for Azerbaijan and Georgia (and maybe Armenia), I thought they were only in Asia and even JetPunk itself says that they are in Asia like on those fill in the map quizzes. I even have this world Atlas book from National Geographic that shows the boundries of Europe and Asia and those 3 countries that I mentioned earlier are in the Asian border so...........
Continents are fairly arbitrary, but most modern definitions divide Asia and Europe along the Caucasus Mountains, which leaves parts of Georgia and Azerbaijan in Europe.
